# Speed of disentanglement

Speed of "disentanglement"

Hi! If two particles are entangled, A and B, and someone messes with A, have scientists determined the speed at which the "signal" that A has been messed with gets from A to B (so B reacts accordingly)? I read that they currently think it's infinitely fast and is permitted to exceed c because no information is transferred. However, at one point we thought light traveled infinitely fast as well. Have they actually proven that it's instantaneous (and if it is, in whose reference frame, if any)?

to the extent of my knowledge, entanglement is spoiled with a rate which is in general the highest rate appearing in the system. This in situations involving atoms implies the polarization decay rate which is somewhat near the classical time on one turn of the electron around the nucleus.
